Yes.

But, its … significantly more complicated than just like, an anime character’s face turns red.

Basically, there’s more actual blood flow going on in your face/cheeks… your body is basically doing something like relaxing many parts of your face, getting more blood diverted to it.

Your cheeks, maybe your forehead, other parts of your face, they actually get warmer, hotter, and if your skin is pale enough, it noticeably changes color in apperance, it reddens.

The emotional experience is akin to embarassment, you’re embarassed how attractive you find whatever it is you are looking at, basically.

Sad Lobster Pyschologist Man isn’t 100% full of shit when he says that blush and rougue… was originally used, in at least some cultures at some points in time, to emulate/exaggerate this.

… but this biological effect is by no means confined only to women… guys blush in exactly the same ways.

I mean shit: A guy going through puberty? (Maybe even long after puberty?) Gets an involuntary stiffy when he’s in close proximity to somebody he finds attractive? He’s probably gonna be blushing with his face too.

Like the hypercartoon version of somebody’s jaw dropping literally to the floor, and their tongue rolling out across the floor… its an extreme exaggeration of the mouth/jaw relaxing, your face forming into a kind of minor smile, or just opening even further agape into a mini O-face… that you might not even realize you are doing.

Its where the phrase ‘jaw-dropping’, as a description of the magnitude of someone’s beauty, comes from.
